javaw and javaw Detection from within Program

[Tom Angioletti]

How can a running java program detect whether java.exe or javaw.exe was used to launch it?

I'm not sure that you can. Why do you need to know this? Maybe we can offer an alternate way of doing whatever it is you are trying to do.

Nevermind, I found a way to do it:

import javax.swing.*;
public class TestJavaw
{
public static void main(String[] args)throws Exception
{
System.out.println("Test");
System.out.flush();
JOptionPane.showMessageDialog(null, "check="+System.out.checkError(), "check", JOptionPane.ERROR_MESSAGE);
}
}
checkError returns true if run under javaw and false if run under java.
I found the suggestion via Google here
